The two parts of this work, which have heretofore been printed separate, are now offered to the Public in one volume, as a system of polite and moral instruction for both sexes: This edition is critically corrected, with the special design of furnishing English schools, at a small expence, with a proper book for reading and parsing their own language, that the teacher may be provided with suitable means for mending the manners of his pupils, while he informs their understandings, by analyzing the grammatical construction, and pointing out the beauties of the most approved style.
